Relationship between protein concentration of lysates from phospho or nonphospho SEM cells and immediate light generation with chemiluminescent substrate is shown. SEM cells in exponential growth (106 cells/ml) were lysed with or without the addition of phosphatase inhibitor to the lysis buffer (phospho or nonphospho lysate). The graph inset corresponding to the shaded area shows high sensitivity and a linear response at the low protein concentration range.Learn more about how we get our images

The PathScan® Phospho-FLT3 (Tyr591) Chemiluminescent Sandwich ELISA Kit is a solid phase sandwich enzyme-linked immunosorbent assay (ELISA) that detects endogenous levels of phospho-FLT3 (Tyr591) protein with a chemiluminescent readout. Chemiluminescent ELISAs often have a wider dynamic range and higher sensitivity than conventional chromogenic detection. This chemiluminescent ELISA, which is offered in low volume microplates, shows increased signal and sensitivity while using a smaller sample size. A FLT3 Mouse mAb has been coated on the microwells. After incubation with cell lysates, FLT3 (phospho or nonphospho) protein is captured by the coated antibody. Following extensive washing, a phospho-FLT3 (Tyr 591) Rabbit Antibody is added to detect the captured phospho-FLT3 protein. Anti-rabbit IgG, HRP-linked antibody is then used to recognize the bound detection antibody. Chemiluminescent reagent is added for signal development. The magnitude of light emission, measured in relative light units (RLU), is proportional to the quantity of phospho-FLT3 (Tyr591) protein.
Antibodies in kit are custom formulations specific to kit.
PathScan® Phospho-FLT3 (Tyr591) Chemiluminescent Sandwich ELISA Kit #7021 detects endogenous levels of phospho-FLT3 (Tyr591) in human cells. This kit detects proteins from the indicated species, as determined through in-house testing, but may also detect homologous proteins from other species.
FMS-related tyrosine kinase 3 (FLT3, also called Flk2), is a member of the type III receptor tyrosine kinase family, which includes c-Kit, PDGFR and M-CSF receptors. FLT3 is expressed on early hematopoietic progenitor cells and supports growth and differentiation within the hematopoietic system (1,2). FLT3 is activated after binding with its ligand FL, which results in a cascade of tyrosine autophosphorylation and tyrosine phosphorylation of downstream targets (3). The p85 subunit of PI3 kinase, SHP2, GRB2 and Shc are associated with FLT3 after FL stimulation (4-6). Tyr589/591 is located in the juxtamembrane region of FLT3 and may play an important role in regulation of FLT3 tyrosine kinase activity. Somatic mutations of FLT3 consisting of internal tandem duplications (ITDs) occur in 20% of patients with acute myeloid leukemia (7).
